Regarding this latest version of your code, this attempt is failing because now you are populating "@files" with full path strings (because you are using th file glob operator, instead of readdir), and then you are appending the path again inside the foreach loop.

Using the file glob is a good idea, so now just fix the open statement:

#!/usr/bin/perl
use strict;

my @files = <C:/Perl/bin/Anti/*>;
for my $file (@files) {
    my count = 0;
    open(MYFILE,"<",$file) or do { warn "Failed to open file: $file:$!
+\n"; next};
    while(<MYFILE>) {
        $count++;
    }
    print "$file has $count lines\n";
}

BTW, I like proper indenting... don't you?
